Correlation of memory characteristics of polymer bistable memory devices with metal deposition process

Abstract

Origin of bistability in organic bistable memory devices (OBDs) was investigated by using two metal deposition processes of electron beam deposition and thermal deposition. Thermal deposition of Al was more effective than electron beam deposition to get high on/off ratio and stable operation of OBDs and metal nanoparticle formation during metal deposition was found to be critical to bistability of polymer OBDs.
